What exactly is the prep kit, my car is wired for the rear window defroster and it bolts in quite tightly. I also bought it from the dealership and they didn't suggest the hardtop prep kit. Perhaps this is the solution to my problem.
Psygnosis let me know how it goes for you.

I found this link with some good photos of the various parts.
Anyone else using the hardtop prep kit?
Cheers
